A high-trust add-in is a provider-hosted SharePoint Add-in that is installed to an on-premises SharePoint farm. It cannot be installed to Microsoft SharePoint Online or marketed through the Office Store. A high-trust add-in uses a certificate instead of a context token to establish trust.
In a production high-trust SharePoint Add-in, the certificate is usually stored in the Windows Certificate Store, and the ClientSigningCertificatePath and ClientSigningCertificatePassword keys are typically replaced by a ClientSigningCertificateSerialNumber key.
